Just installed Canon Selphy 780 CPP on a PowerBook, worked fine from iPhoto. Then my husband left it connected for several hours, laptop went to sleep. Later he couldn't print from within iPhoto, just got the "jobs stopped" message. Even after disconnecting printer, restarting laptop, it doesn't seem to want to print from within iPhoto 8.0.
Cleared print jobs in printer menu, but is there somewhere else to clear this? Still shows jobs on hold, but won't print new photos to Selphy.
It will print photos exported from iPhoto and used in Canon's print software, but that's a pain, want to print from iPhoto.
Had a similar problem with an old Epson PictureMate compact photo printer.
